    3 Installation This section covers instructions on installation and commissioning. Installation of the device must be carried out by trained, qualified specialists authorized to perform such works. CAUTION When removing the instrument from hazardous processes, avoid direct contact with the fluid and the meter All installation must comply with local installation requirements and local electrical code 3.1 Selecting the Installation Location...
  • Page 14: Clamp Connection

    3.2.1.1 Clamp Connection Choose gaskets that meet specified standards to avoid excessive clamp locking and squeezing gasket. Excessive locking of clamp may damage the sensing diaphragm and cause measuring error. NOTE Engage process connection with a minimum of 7 thread connections and tighten the housing rotation set screw to prevent it from rotating Housing Rotation To ensure the visibility of LCD display...
  • Page 15: Conduit Installation

    Conduit Installation Improper sealing of connections may damage the transmitter due to excess moisture accumulation. Mount the transmitter with electrical housing positioned downward so that the excess of moisture is condensed and drained out from the casing. Secondly, install wiring with a drip loop and ensure the bottom of the drip loop is mounted lower than the conduit connections or the transmitter housing to avoid moisture accumulation in the housing.
  • Page 16: Zero Point Adjustment

    Zero Point Adjustment For sensor zero trim, ensure that the vessel is empty and there is no input medium pressure on the diaphragm. The vessel should be applied a normal atmospheric pressure. If applying external pressure to the transmitter make sure that the display is sufficiently stabilized (after approximately 10 to 15 seconds), before initiating any trim function.
  • Page 17: Steam Flow Measurement

    Steam flow measurement For steam flow measurement, up-tilt the guiding pressure tube by 45°. Ensure that transmitter installation location is at lower level than that of the process pipeline. Pre-inject cooling liquid into the guiding pressure tube. Slowly open the shut-off valve to start measurement.
  • Page 18: Electrical Connections

    4 Electrical Connections This section covers the all electrical connection requirement. Electrical connection of the device must be carried out by trained, qualified specialists authorized to perform such work by the installation site. WARNING Connect all electrical cables when the power is switched off. If the device does not have switch-off elements, then, overcurrent protection devices, lightning protection and/or energy isolating devices must be provided by the customer.
  • Page 19: Power Supply Specifications And Connection

    4.2 Power Supply Specifications and Connection Use independent linear direct current power supply for pressure transmitter. Large resistive load results in high pressure drop. Therefore, it is recommended to consider the resistance across the signal cable, display meter and other equipment to ensure sufficient voltage is provided to the pressure transmitter for its normal operation.
  • Page 20: Cable Protection System

    Power Supply Connections 4.3 Cable Protection System Apply following cable protection measures to protect the connecting cables from various factors that affect negatively on the cable lifetime. Standard Protection System To avoid liquid flowing along with the cable into the terminal box, configure a U-shaped ring between pull box and pressure transmitter as shown in the figure below.
